I got procps working I think (both with and without the revert).
I think the problem might just be that I wasn't also copying the rebuilt /bin/cygprocps-8.dll to match the /bin/procps.exe. There's some tricky renaming that make install does, so I did 'make install DESTDIR=/tmp/install' and copied just those two files. I'm guessing it would all work on a properly fully installed build.
